Olympic Adventure 42 Information, Review, Specs

While the Olympic Adventure 42 shares its hull lines with the North American-built Whitby 42, it was tailored for the European and Mediterranean markets, often featuring slight variations in ballast and interior joinery. The yacht was built using traditional hand-laid fiberglass techniques, which, combined with its heavy displacement, gives it the "overbuilt" reputation common among offshore yachts of that era.

Sailing Performance & Handling

Under sail, the Olympic Adventure 42 is characterized by its predictable, sea-kindly motion, a direct result of its heavy displacement and moderate sail area-to-displacement ratio. As a ketch-rigged vessel, it offers a versatile sail plan that is particularly advantageous for short-handed crews. In heavy weather, sailors can employ the "jib and jigger" configuration—sailing under the headsail and mizzen alone—which keeps the center of effort low and balanced, reducing heel and making the boat easier to steer.

The hull's design emphasizes tracking over agility. According to design notes from the Ted Brewer Yacht Design archive (which discusses the sister Whitby/Olympic 42 hull), the moderate draft of approximately 5 feet 6 inches allows the boat to access shallower cruising grounds while maintaining enough bite to windward. However, like many heavy-displacement cruisers of this vintage, the Adventure 42 is not a "pointing" boat; it performs best on a reach or a run. In light air, the yacht’s significant wetted surface area can make it sluggish, often requiring the iron sail—typically a Lehman or Perkins diesel—to maintain pace.

Interior Comfort & Variations

The center-cockpit configuration is the defining feature of the Adventure 42’s layout, providing a spacious and private master cabin aft. Unlike some center-cockpit designs of the 1970s that required transitioning through the cockpit to reach the stern, the Olympic Adventure 42 features a dedicated walkthrough passage below decks, usually housing a sea-berth or providing easy access to the engine room.

The main salon is traditional, featuring a U-shaped galley that is well-secured for cooking at sea and a navigational station that would be considered oversized by modern standards. The use of heavy teak and mahogany joinery was standard for Olympic Marine during this era, creating a warm, nautical ambiance.

Variations of the 42-foot hull include the Olympic Sea 42, a later and more modern evolution that utilized advanced materials like Aramat K. While the Adventure 42 focused on the ketch-rigged, traditional aesthetic, the Sea 42 was often configured as a sloop or cutter with a more contemporary interior.

Known Issues & Buyer’s Checklist

Prospective buyers should approach an Olympic Adventure 42 with a focus on structural longevity, as many of these vessels have spent decades in high-UV Mediterranean environments.

1. Chainplate Inspection: The chainplates are integrated into the hull structure; any signs of weeping or rust streaks on the interior bulkheads suggest water ingress that could compromise the core or the fasteners.
2. Osmotic Blistering: Early Greek-built fiberglass hulls from this era are known to be susceptible to osmosis. A professional moisture meter reading and a "tap test" of the hull are essential during survey.
3. Teak Deck Longevity: If the vessel is equipped with the original laid-teak decks, they are likely nearing the end of their service life. Leaks through deck screws can lead to core saturation in the sub-deck, a costly and labor-intensive repair.
4. Fuel and Water Tanks: The original tanks are often made of mild steel or aluminum and may be glassed into the structure or tucked under the cabin sole. Inspecting these for corrosion is vital, as replacement often requires significant joinery removal.
5. Rudder Bearings and Skeg: Given the boat’s age, the skeg-hung rudder should be checked for "play" or lateral movement, which indicates worn bushings or potential issues with the rudder post.

Community & Resources

Owners of the Olympic Adventure 42 often find technical commonality with the Whitby 42 community. The Whitby Brewer Association serves as a primary repository for technical drawings and refit advice that applies directly to the Olympic-built variants. Additionally, the shipyard itself, Olympic Marine, still operates as a major marina and refit center in Lavrio, though they have transitioned their manufacturing arm to the Omikron Yachts brand.

The Verdict

The Olympic Adventure 42 remains a formidable choice for sailors seeking a "tank-like" cruiser capable of crossing oceans on a budget. While it lacks the speed and interior brightness of modern production boats, its structural integrity and balanced handling in a gale offer a level of security that is hard to find in newer, lighter designs.

Pros:

• Sea-Kindliness: Heavy displacement and ketch rig provide a comfortable motion in offshore conditions.
• Privacy: The center-cockpit layout offers excellent separation between the master aft cabin and forward guest V-berth.
• Build Quality: Substantial fiberglass layup and high-quality interior woodwork from the golden era of Greek shipbuilding.

Cons:

• Light Air Performance: Struggles in winds under 10 knots without significant engine assistance.
• Maintenance Intensity: Older systems, aging teak decks, and potential osmosis issues require a dedicated maintenance budget.
• Maneuverability: The long keel and displacement make backing into tight Mediterranean slips a challenge without a bow thruster.
